if you can't please skip it The US Central Intelligence Agency is designing a newgeostationary spy satellite. Geostationary satellites remain in afixed position relative to some point on Earth because they areplaced in orbit 3.6 *107 meters above the Earth's surface Thissatellite is to be equipped with a high resolution, widefield-of-viewdigital camera that will create JPEG images to be transmitted overa 10 Mbps full-duplex microwave link back to a computer at itsbase station on Earth The propagation speed of this link is 24 *108meters/second. The satellite transmits each image as a stream of37 *106 bits along with a very small header that contains achecksum computed over the image contents When the image hasbeen received at the base station, the computer then computes achecksum over the received image and compares it with thechecksum calculated at the satellite. A small acknowledgementmessage is sent back to the satellite over the microwave linkindicating whether or not the image was received correctly If theimage was not received correctly the entire image is retransmittedfrom the satellite If the image was received correctly, the cameracan then immediately begin to acquire a new image and transmitthe next stream of bits to the ground station In answering thefollowing questions, show how you derived your results including allintermediate values you used in the calculations Assume notransmission errors occur and that transmission and processingtimes for the checksums and acknowledgements are negligıbleIn answering the following questions, show how you derived yourresults including all intermediate values you used in thecalculations. Assume no transmission errors occur and thattransmission and processing times for the checksums andacknowledgements are negligiblea) How many images can the satellite transmit per minute?b) For tracking small-scale movements on the ground it is desirableto have the satellite successfully transmit at least one new imageeach second. What is the largest image size allowed (how manybits can each image contain) in order to meet this requirement?c) Consider increasıng the transmission speed of the microwavelink to 100 Mbps while the propagation speed remains at 24 *108meters/second. What is the largest image size that can still meetthe requirement of transmitting one new image each second?

User Satisfaction team wants to send monthly summaries for each user. They need the following details with the user ID: The last day of the month when the users traveled most recently One week after the last day of the month when the users traveled most recently You need to return a three-column output with USER_ID, LAST_TRAVEL_MONTH and NOTIFICATION. LAST_TRAVEL_MONTH should be calculated using the MAX of the LAST_DAY of the TRAVEL_END_TIME field. Similarly, NOTIFICATION should be calculated with DATE_ADD function to add one week.
